A horizontal axis fine-tuning device for laser tracking measurement system

Abstract

The invention discloses a horizontal axis fine adjustment device for a laser tracking measurement system and belongs to the field of laser measurement. The horizontal axis fine adjustment device mainly comprises three parts. The first part is a micro motion part in front and back directions of a horizontal plane, and the front and back micro motion of most the structures including a support plateis realized through rotating a horizontal axis horizontal direction adjusting mechanism 2. The second part is a guiding part whose main structure is a bottom plate, and the relative position of the bottom plate to the entire laser tracking measurement system in the fine adjustment process is unchanged. The third part is a support plate horizontal state balance adjustment part which mainly includesa fastening screw, a cylindrical pin and a spring. The device is a fine adjustment device in the laser tracking measurement system based on unchanged relative position of a standard ball, and a horizontal axis and a vertical axis are intersected by the front and back fine adjustment of a horizontal rotation axis. The micro motion of a pitch axis in the front and back directions in the horizontalplane is achieved through the horizontal axis fine adjustment device, and the measurement accuracy of the laser tracking measurement system is improved.

[0002] Laser interferometer is currently the most accurate practical tool for large-scale displacement measurement in the world. The flexible coordinate measurement system based on multiple laser tracking interferometry devices avoids the limitation of traditional coordinate measuring machines using precision guide rails, and is considered to have the most potential. It is a large-scale, high-precision, non-contact, dynamic, and on-site real-time measurement tool. At present, its application has been extended to various fields in the industry, but different measurement optical paths must be built when measuring different errors, especially for CNC machine tools and When the coordinate measuring machine is calibrated, the detection cycle of using laser interferometer to measure various errors is long, and the measurement efficiency is low. Therefore, it is efficient and convenient, and the laser tracking measurement system specially used for the calibration of CNC machine tools and coordinate measuring machines came into being. pregnancy
